INCINERATOR.

Application filed February 19, .1924. Serial No. 693,861.

To all whom; may concern:

Be it known that'I, ,SAMUEL A. DUGAN, 'a'

"citizen of the United States, residing .at

Galveston, in the county of Galveston and State of Texas, have invented certain new and useful Improvements, in Incinerators, of which the fgllowing is a full, clear, and exact specificatlon. 1

This invention relates to incinerators especially designed for use in homes for burning trash, garbage and slops in order to prevent breeding of flies and mosquitoes, 'to

starve rats, mice and bugs, and to prevent the accidental starting of destructive fires in or about the homes. These incinerators may be made in different sizes adapting them for use in school yards, public parks, public auto mobile camps, railroad stations, hotels and restaurants, in fact, anywhere that'rubbish and trash'accumulates, even on public drives where the incinerators may be placed at intervals and trash hauled to each one for burning, the ashes being utilized for fertiliz ing flower beds on highways or in parks.

It is they object of the present invention to, provide an incinerator of simplified and improved constructionwhich is inexpensive to manufacture and which may be used effectively for burning 'slops and garbage as well as trash, so that said slops and garbage cannot be eaten by rats, roaches, flies, or

other vermin. A special object is to construct the incinerator in sucha way that the.-'

burning of the trash will aid in burning the garbage and slops. Another special object is to arrange-the parts of the incinerator so that it may be utilized for burning trash alone if desired. Other objects will appear ,as the description proceeds. l

The inventionwill be first hereinafter de-' scribed in connection with the accompanying drawings, which constitute part of this specification, and then more specifically defined in the claims at the end of the description.

Figure, 5 is a section on the line VV of Figure 2. i

' Figure'6 is a vertical section of the upper portion of the incinerator taken on the line VI VI of Figure 4 and showing the cover raised and supported by the hook, and

Figure 7 is a section on the line VII-VII of Figure 2 and showing the draft door raised.

The body 1 of the incinerator is preferably made of sheet iron in vertical cylindrical form, and is supported above the ground by a plurality of legs 2, three of which are shown in the drawings spaced equidistantly about said body and formed of angle iron extending upward along said body to which they are riveted at 3 and An ashof'the body 1, and said opening is normally closed by a slide 6 mounted on the inner edges of double edged runners 7 at the sides of the openingand below the bottom 5.

In linev with the outer end of the slide 6, a'draftopening 8 isformed in the side of said body 1, anda vertically movable door 9 is fitted over said draft opening, being guided at its edges in grooves 10, see Figure'3. Said closure 9 has a handle portion 11 projecting outwardly at its upper end, and a vertical series of perforations 12 are formed in said door in line with a perforation 13 in the wall of the body 1 above the opening 8, whereby the door 9 may be supported at dilferent levels by inserting a pin 14' through said perforation 13 and any one of the perforations 12 in order to regulate the draft. 1 An ash pan 15 is mounted below. the ashdump opening 4 and preferably supported on the outeredges of the runners 7 by angle irons 70 suitably secured along-the lateral edges of said pan which is used for catching the ashes when the incinerator is used inthe house. When the incinerator is used. outdoors, the ash pan may be omitted and the p vided. w th a mo l c er 1 ha ing a handle 18, said cover conforming at its inner end to the curvature of the body 1 and having a'downwardly turned fiangej19 at'its sides and outer end to of-said chute.

A cover 20 is hinged at 21 to the body l, and at a diametrically opposite point on said cover there is secured'a metal strip 22 projecting a short distance beyond the edge of the cover and having a hook 23 pivotally connected to its projecting end portion, as best shown in Figures 1, 4 and 6. When the cover 20 is swung upward on the hinge 21, as shown in Figure 6, the hook 23 is engaged with a perforation 24 in the upper portion of the angle iron of the adjacent leg'2 for supporting said cover in its raised position.

The cover 20 has a central opening 25 in which a smoke stack 26 is fitted and secured by external angle brackets 27 and an internal flange 28 .on thelower end of said stack. The upper end of the stack 26. is fitted with a cap-29 of wire mesh material to 'arrest sparks without'interfering with the draft,

Within the body 1 of the incinerator and removably supported on angle brackets 30 preferably arranged slightly above the level of the top of the trash chute 16, a perforated plate 31 is placed for holding wet garbage and slops to be burned by the fire from= I v thetrashintroduced into the'bottom portion of said body'throughsaid chute 16. Said perforated slop plate 31 has a central opening 32 in which is removablymounted a short supplemental-stack 33. which is-of less diameter than the main stack-26 and which extends concentrically into the lower end of sald'main stack, see Figure 2. Said supplemental stack 33 has angle brackets 34 riv? eted thereto and spaced slightly, above its rlower'end for supporting the same on the slop plate 31 with the lower end, portion of said short stack extending down through the central opening 32 in said plate. It will be noted that the upper end portion of the short stack. 33 is spaced inward from the walls of v the lower end portion -'of the inain stack 26 so that the main draft up through the short stack to the main stack will induce a secondary draft up through theperforation in the plate 31 .and. around the upper portion of the short stack which extendsinto the lower end portion of said upper stack; This induced or 'secondary draft serves to burn or incinerate' the wet garbage and slops which are placed on the perforated plate 31,"while the direct draft up through the short stack 33 to-the main stack 26 supports the combustion of the trash in the bottom portion of the incinerator so that the burning thereof will not be stopped by the mois- Il ture in the wet garbage or slops, and the fire Q from said burning trash may-consequently be utilized for effectively wet garbage and slops.

fit over the upper edge incinerating said -When the cover 20 the incinerator is I swung open, as illustrated in Figure 6, and already described herein, wet garbage and slops may be readily placed on the perforatedplate 31 around the short stack 33. In case only trash is to be burned, the perforated plate 31 and short stack 33 may be ,taken out through the open upper end of the incinerator, and the latter may be then filled with trash from the topas well as through the chute 16, the draft then being directly up through the main-stack 26.

Referring again to the draft door 9, it will be noted that it is illustrated in raised po sition in Figure 7. It will also be noted in- Figure 1 that the pin 14 when not in use may be hung by a wire 34 from the hand portion 11 of said draft door 9.
